Personally, I like them.
The first one, how her being cropped out too much was mentioned, puts more focus on her hand on his chest with the engagement ring on her finger. Makes me think of an ad for a jewelry store, and their commitment to each other more so than just seeing a couple kissing.
The second one I like also. I think the focus, composition and exposure are on spot for my taste. The watermark, in my opinion is a bit distracting in the first two, I will agree.
The third one I like also but not quite as much. Maybe the colors or him being cropped out just a hair bit bothers me, but I do like what you did with the watermark in the third one much better than the ones in the first two.
I love film prints. Love love love them! I think you did very well with the noise on these, not overboard and not so distracting as to take away from the quality of the photos and just enough to make it look similar to film grain.
Just my opinion. I don't claim to be smart, or know what I'm talking about, so take it with a grain of salt, and keep up the good shooting!
